Iis susceptible to Aphanomyces root rot. In NY, Guardsman II averaged 1.25 Mg/ha per year more dry forage than 'Oneida VR', 1.95 Mg/ha more than 'Vernal', and 1.86 Mg/ha more than 'Alfagraze' in three production years. Concentrations of crude protein, neutral detergent fiber, and acid detergent fiber are between those of the high quality check cultivar WL 322HQ and '5432'. Flower color of the Syn. 2 generation is 97% purple, 3% variegated, and a trace of yellow, cream, and white.
